Get external page title from url

Question

Code:

<input type="text" id="url_value"/>
<input type="button" id="get_title" value="Get title"/><br/>

<span class="url_title"></span>

Is there a way to put any url on the text input, get the page title and show it on the span without going to that page?

Example: If I put the url of this page: Get external page title from url, I get the page title: php - Get external page title from url

It's called `cURL` my friend: http://stackoverflow.com/questions/3711357/get-title-and-meta-tags-of-external-site — chriz, Mar 26 '13 at 15:02
JS cannot directly reach out to external sites to retrieve content. That's a violation of the same origin security policy. You can, however, have your server fetch the page title and send it over to the JS via ajax. — Marc B, Mar 26 '13 at 15:02

<?php
$page = file_get_contents($_REQUEST["url"]);
$title = preg_replace('/<title>(.*)</title>/i', '$1', $page);
echo htmlentities($title);
?>

With this code you need to activate allow_url_fopen php.ini directive.

WARNING: try to make a list of secure website and allow to get title only in their pages, to avoid XXS attacks.
